Described as "especially glorious... ethereal" by Whole Note, and "a highlight of the concert" by the Boston Musical Intelligencer, the music of Canadian composer Tawnie Olson is performed on four continents by a wide range of ensembles and individual musicians. She is the winner of the 2015 Iron Composer competition, and has received awards from the SOCAN foundation and the Guelph Chamber Choir/Musica Viva. Her composition Scel lem duib, for chamber chorus and harp, was selected for publication in the National Collegiate Choral Organization's 2013 choral music series; other scores are available from the Canadian Music Centre, E.C. Schirmer (O Inexpressible Mystery - forthcoming) and Mark Foster (Spring and Fall: to a young child - forthcoming).
